NOTES, 
BOTANY. 
Irish Water-plants. 
From some notes made by Professor Hugo Gliick, of Heidelberg, in 
Ireland last 5^ear, and recently received from him, I extract the following ; — 
Ranunculus Flammitla var. alismifolius Glaab, — Rosslare, Co. Wexford, 
with R. hederaceiis ; at Weir Bridge, near Tuam, N.E. Galway. 
Oenanthe fluviaiilis, Colem. — Weir Bridge, N.E. Gahvay (/. sithmersa and 
also half submerged forms). 
Vtricitlaria ochroleuca, Hartm.- -Sparingly in Glendalough Lake, Recess 
(deep-water form), and between Recess Hotel and Station (shallow - 
water form), W. Galway. 
Alisma Plantago x ranunculoides. — Turlough Bog, near Tuam, and between 
Turlough Bog and Tuam, N.E. Galway. 
Alisma ranunculoides f. zosterifoUus Fr. — Near Recess, W. Galway, and 
near Tuam, N.E. Galway.

Ammi majus in County Down. 
A colony of about twenty individuals of this plant was discovered in 
June, 191 2, in the County of Down, near Strangford Lough, b}^ an Enghsh 
botanist, Dr. F. W. Stansfield, of Reading. Some of the plants 
were in flower, and I had the pleasure of exhibiting a young plant from 
the locality to the members of the Belfast Naturalists' Field Club, at 
their meeting on the 19th of November. The leaves of this plant bear a 
great resemblance to the fronds of Ptcris semilata, and the likeness was 
distinct in the youn^ plant, Avhich might easily have been taken for a 
young fern of the above species. The leaves are diflerent from those of 
any other Urnbellifer found in the British Islands, being bi- to tri-primately 
parted into oblong or oblanceolate acutely serrulate leaflets. It grows in 
sandy soil, and has a very long tap root. Ammi majus is noticed in the 
second edition of " Cybele Hibernica," p. 490, as follows : — " Portmarnock 
Sands,'i82i. — Mack. Cat. — Seen here for several years in succession, by Mr. 
John Bain. A casually introduced plant of Southern Europe, which has 
long since disappeared." It does not seem to have been found elsewhere 
in Ireland, as there is no mention of it in Praeger's Irish Topographical 
Botany. It is remarkable that Ammi majus, which is a native of the 
Mediterranean littoral, has been found in County Down, growing not very 
far from- another plant, also a native of the shores of the Mediterranean, 
viz., Glyceria festucaeiormis. Concerning this Glyceria there was some 
correspondence in the Irish Naturalist, 1904, pp. 72, 79, where I advocated 
the view that the grass had probably been introduced with barley imported 
to Comber distillery from a Mediterranean port ; it is curious now to find 
another plant from that region established in County Down.
